RADIATOR THERMOSTATS
PRODUCT DATA
Application
A Radiator Thermostat is installed onto a Thermostatic Radiator Valve Body (TRV body). The combination of both, the
Thermostatic Radiator Valve (TRV), controls the room temperature by adjusting the flow of hot water through a radiator.
TRVs are installed in water-based heating systems on the
supply or, less commonly on the return connection of radiators.
Radiator thermostats of this type fulfill the European Standard
EN 215 when used with certified Honeywell TRV bodies.
Honeywell radiator thermostats with Honeywell (HW) M30 x 1.5
connection are suitable for all TRV body and radiator inserts
with M30 x 1.5 connection and 11.5 mm closing dimension.
Features
• Conforms with M30 x 1.5 connection to European standard EN 215
• Equipped with wax sensor
• Over-temperature protection
• Modern, ergonomical design with red economy button
for optimal setting
• Compact size

Specifications
Thermostat connection M30 x 1.5
Setpoint range 0 - ❄ - 1..6
Temperature range 1...26°C (34...79°F)
Closing dimension 11.5 mm
Function
Radiator thermostats of this type control the TRV body. The air
passing around the sensor of the radiator thermostat causes
the sensor to expand when the temperature rises. The
expanding sensor closes the TRV accordingly. When the room
temperature changes the TRV opens or closes proportionally.
Only the amount of water required to maintain the room temperature set on the radiator thermostat is allowed to flow through
the valve.

NOTE: All °C and °F-values approximate. Heating can freeze when radiator thermostats with zero-position are set at position '0'.
Zero-position is also thermostatically controlled - when temperature falls the TRV may open.
